Kylie Minogue opposes Kylie Jenner's attempt to trademark 'Kylie'

Can there be only one Kylie?

Jenner is hoping to lay claim to the name, which she has successfully used to sell makeup kits, books and a slew of other products. She's attempting to trademark the name in the U.S., for "advertising services, namely, promoting the brands, goods and services of others; endorsement services, namely, promoting the goods and services of others."

But singer Kylie Minogue is none too thrilled. According to documents, KDB Pty Ltd. filed a Notice of Opposition on behalf of Minogue on Feb. 22, claiming that granting Jenner the desired trademark would dilute Minogue's brand. It also mentions that the singer is "known worldwide simply as 'Kylie,'" and that Minogue registered the domain www.kylie.com in 1996.

Along with establishing Minogue's longtime presence, the notice is quick to shade Jenner, calling her a "secondary reality television personality who appeared on the television series Keeping Up With the Kardashians as a supporting character, to Ms. Jenner’s halfsisters."

The notice also mentions Jenner's social media accounts "where her photographic exhibitionism and controversial posts have drawn criticism from, e.g., the Disability Rights and African-American communities," referencing a cover of Interview for which Jenner posed in a wheelchair.

It's not uncommon for celebrities to file for trademarks to protect their brands, though the system is murky and disputes often ensue. Beyonce and Jay-Z filed a bid to trademark 'Blue Ivy,' a few days after their daughter's birth to reserve it as a potential brand name for baby products. It was challenged by a wedding planner of the same name, who was permitted to continue using 'Blue Ivy' in marketing material for her company, though 'Blue Ivy Carter' may be fair for Bey and Jay to reserve. Confusing, right?

Minogue, however, doesn't seem to think it should be so challenging in this case.

Tweeting her position, the singer referenced the title of her album released in 2000, and perhaps the fact that she's been making "Kylie" a household name since she started doing The Locomotion back in the '80s. Long before Jenner was even born.
